NEW PRODUCT – Saleae Logic 16 – 16-Channel USB Logic Analyzer

NEW PRODUCT – Saleae Logic 16 – 16-Channel USB Logic Analyzer! A logic analyzer is a device that lets you watch digital signals in your electronics project. You can watch them real-time or log the data for later perusal. Unlike an oscilloscope, its not good for measuring analog signals – but also unlike an oscilloscope, you can track 16 signals at time! So its a good complementary tool. This logic analyzer plugs into a computer and has easy to use cross-platform software. This makes it small, portable and inexpensive. If you ever have to to debug SPI, i2c, serial, CAN, 1-wire, Manchester, biphase or other digital protocols, this tool is essential!

  • Speedy 100MHz
    Logic samples each channel at up to 100 million times per second! The sample rate is flexible and based on number of channels: Sample 2 channels at 100MHz, 4 channels at 50MHz, 8 channels at 25MHz, or all 16 channels at 12.5MHz. A large fraction of practical, real world applications run at less than 10MHz, and Logic is ideal for these.
  • 16 Channels
    Logic16 has 16 inputs — it can monitor 16 different digital signals at once. For many modern microcontroller-based designs, this is plenty.
  • 10 billion samples
    Logic can save as many as 10B samples, letting you capture even the most elusive events. No more dealing with frustratingly small sample buffers.
  • 1.8V logic welcome Works with 1.8V to 5.0V logic levels
  • Comes complete
    Start debugging within 5 minutes of opening your new Logic; everything is included: An ultra-flexible 22AWG 64/40 wire harness, 18 high-quality micro-hook probes, a USB cable (2 meter mini-B to A), and a nice carrying case. Download the software from our site (see software)
  • Enclosure
    We love well made tools. That’s why we make Logic16’s case out of custom CNC machined aluminum and make sure its anodized surface is finished to perfection.
  • Protection
    Logic’s inputs are protected against over-voltage conditions via current-limiting resistors and ultra-low-capacitance diode clamps. A resettable fuse protects the USB ground return line to augment the USB host’s existing protection.
  • Worry free
    Logic16 comes with a 2-year warranty direct from the manufacturer as well as email support

Geometry and Weight

  • Length & Width: 3.12 inch (79.2mm)
  • Thickness: .39 in (9.8mm)
  • Volume: 3.8 in3 (62.2 cm3)
  • Weight: 2.6 oz (73.7 gm)

Input Voltages and Thresholds

  • Input voltage range: -0.9V to 6V
  • Works with 1.8V, 2.5V, 3.3V, and 5V systems
  • Threshold Setting 1 (for 1.8V to 3.6V)
    • Input Low Voltage:
    • Input High Voltage: >= 1.4V
  • Threshold Setting 2 (for 5V)
    • Input Low Voltage:
    • Input High Voltage: >= 3.6V
  • Over-voltage protection to +/- 50V. Not meant for continuous operation outside -0.9V to 6V.
  • ESD protected per CE requirements

Input Impedance

  • 180Kohm || 7pF (typical, approximate)

Maximum Input Bandwidth

  • 25MHz square wave

Crosstalk Immunity

  • Tolerant of simultaneous switching on up to 8 channels at all voltages.
  • Note that unused inputs may exhibit crosstalk if left floating. If desired, unused inputs can be disabled.

Error/Accuracy

  • Pulse-width measurement: +/- 10ns @ 100MHz, +/- 20ns @ 50MHz, +/- 40ns @ 25MHz, +/- 80ns @ 12.5MHz

Maximum Sample Rates

  • 100MHz when using 2 channels, 50MHz when using 4 channels, 25MHz when using 8 channels, and 12.5MHz when using 16 channels. Note that achieving the highest sample rates requires low USB latency; this may not be achievable on all computers. Performance may improve with the removal of other USB devices, using a different USB host controller, or increasing the software’s process priority.

Available Sampling Rates

  • 100MHz, 80MHz, 50MHz, 40Mhz, 32MHz, 25MHz, 16MHz, 12.5MHz, 10MHz, 8MHz, 6MHz, 5MHz, 4MHz, 2MHz, 1MHz, 500KHz, 250KHz

Sample Depth

  • Up to 10B samples. Absolute maximum depends on data compressibility, available RAM and operating system. 10B samples assumes reasonably high compressibility.

Pre-ship Testing

  • Automated testing against long pseudo-random waveforms at 1MHz and 25MHz, run at 1.8V, 2.5V, 3.3V and 5V.

System Requirements

  • Windows XP (32-bit)
  • Windows Vista (32-bit or 64-bit)
  • Windows 7 (32-bit or 64-bit)
  • Mac OS X 10.4 Tiger or higher
  • Linux: recent Ubuntu, Fedora, or openSUSE. Other distributions are likely to work but not specifically supported.

Safety & Equipment Protection

  • Logic16 may not be used with DUTs (devices under test) which are not electrically isolated from MAINS (i.e. wall power).
  • DUTs which are battery powered, or USB powered (from the same computer as Logic16) are acceptable.
  • DUTs powered by AC adapters which have only 2 prongs, and do not have an earth ground connection (such as most “wall warts”), usually provide MAINS isolated power and are acceptable.
  • For other DUTs, isolation can typically be achieved through the use of a dedicated isolation transformer (such as those made by Tripp-lite).
  • When using USB powered DUTs, special care should be taken to avoid connecting USB sourced power to Logic16’s ground, as this provides a short-circuit return path. While both Logic16 and USB ports are designed to survive a short circuit event, care should be taken to minimize its likelihood.

  1. I have contacted Saleae in the past to tell them not to recommend Tripp-lite isolation transformers because they are power conditioning only and they strap the secondary windings of the transformer to earth ground inside the box. This means you are not using an isolation transformer in the tech vernacular and are still able to kill your equipment or yourself. See my blog and video on this:
